We report an attempt to measure the ionic charge state of solar energetic oxygen ions at energies of 8-20 MeV /nuc. This study is part of a cooperative project of the space agencies of the USA and the USSR, in which we compare data from cosmic ray experiments on IMP-8 and ISEE-3 outside the magnetosphere with data from a series of experiments on Cosmos satellites in low earth orbit. From these comparisons, we determine the orbit-averaged geomagnetic transmission of these particles, which can be related to the average ionic charge state. We present preliminary results on the three solar energetic particle events analyzed to date.
